Peel the onion and grate it in a bowl.
Squeeze the onion completely and save the juice. Place the squeezed onion in a large bowl.
Soak the bread in the onion juice for about 10 minutes.
To the grated onion, add ground beef, chopped parsley, cumin, coriander, salt, pepper, cinnamon and dried mint. Mix well to make sure all the ingredients are well mixed.
Add in the soaked bread and mix well. Knead the meat mixture using your hands.
Cover the bowl with a plastic wrap and place the bowl in the fridge for 30 minutes to 1 hour.
Heat the olive oil in a pan over medium heat.
Form the meat mixture into patties and sear in the pan for about 4-5 minutes on each side.
Serve with warm pita, yogurt sauce, fresh tomatoes, onion and cucumbers.
